The Mongol Empire emerged from the unification of several nomadic tribes in the Mongol heartland under the leadership of Temüjin, known by the more famous title of Genghis Khan (c. 1162 – 1227), whom a council proclaimed as the ruler of all Mongols in 1206. The empire grew rapidly under his rule and that of his descendants, who sent out invading armies in every direction. The vast transcontinental empire connected the East with the West, and the Pacific to the Mediterranean, in an enforced Pax Mongolica, allowing the exchange of trade, technologies, commodities, and ideologies across Eurasia.
The empire began to split due to wars over succession, as the grandchildren of Genghis Khan disputed whether the royal line should follow from his son and initial heir Ögedei or from one of his other sons, such as Tolui, Chagatai, or Jochi. The Toluids prevailed after a bloody purge of Ögedeid and Chagatayid factions, but disputes continued among the descendants of Tolui. The conflict over whether the Mongol Empire would adopt a sedentary, cosmopolitan lifestyle or continue its nomadic, steppe-based way of life was a major factor in the breakup. (Full article...)
The Irghiz River skirmish was a minor engagement fought between forces of the Khwarazmian Empire and the Mongol Empire during the early 13th century. While the occurrence of the skirmish itself is well-attested, its precise dating is uncertain, since the major chroniclers of the period give differing accounts. Modern historians have proposed two possible dates: 1209 or 1219. The background events are similar for each possible date: Genghis Khan, khagan of the Mongols, sent an army under his general Subutai to attack hostile forces (either a Merkit confederation or the renegade Naiman prince Kuchlug) in the former lands of the Qara-Khitai dynasty. Shah Muhammad, the ruler of the Khwarazmian Empire, received news of large armies operating along his northern borders and set out to confront them.
The Mongol army, which possibly also included the general Jebe and Genghis' eldest son Jochi, was surprised by the Shah very soon after defeating their initial target; Muhammad rejected peace overtures and initiated battle. The fierce engagement, between two armies of approximately equal strength, lasted until nightfall, but the Mongols probably had the upper hand. However, since they had been instructed to avoid any possible fighting, they abandoned their camp in secret during the night. The prowess of the Mongol soldiers displayed during the skirmish has been cited as a major reason for the Shah choosing a defensive strategy during the open warfare of 1220–21, for which this was a preliminary encounter.

The Battle of Köse Dağ took place in eastern Anatolia on 26 June 1243 when an army of the Sultanate of Rum, led by Sultan Kaykhusraw II, confronted an invading Mongol army under the general Baiju and was decisively defeated. The battle was the pivotal event of the Mongol conquest of Anatolia: Rum, previously a significant independent power in the eastern Mediterranean, was reduced to the status of a client kingdom, and its territories were later formally annexed by the Mongol Ilkhanate.
The Mongol Empire first achieved territorial contact with the Sultanate in the early 1230s by conquering a large swathe of western Iran, but largely left it alone over the next decade. Instead, under their general Chormaqan, Mongol armies subjugated Transcaucasia and reduced the Kingdom of Georgia to a vassal state. After the accession of Kaykhusraw II to the Rum throne in 1236, relations deteriorated, and Mongol raids on Rum territory began in 1240. Two years later, Baiju, who had replaced Chormaqan after the latter became disabled, captured and pillaged the city of Erzurum, escalating hostilities into open war. (Full article...)
After his father Muhammad II had died on an island in the Caspian Sea, Jalal al-Din assumed the title of Khwarazmshah and travelled eastwards. Escaping the Mongols several times, he reached Ghazni and started assembling a large force; he then defeated the Mongol commander Shigi Qutuqu at the Battle of Parwan. This upset victory drew the attention and ire of Genghis Khan, who gathered a force of at least 50,000 and moved towards the Shah, who had lost a large proportion of his force because of a dispute over plunder. Now unable to effectively combat the Khan, he retreated eastwards towards the Indus river; the Mongols caught up to the Khwarazmians on the morning they were due to cross the Indus. (Full article...)
The region Khorasan contained Silk Road cities such as Merv, Nishapur, and Herat, which were among the largest and richest in the world. Tolui systematically besieged and captured them in turn, pillaging their wealth and executing their inhabitants. Although modern historians regard the figures of medieval chroniclers to be vastly exaggerated—one account has 2.4 million people killed in Nishapur alone—the figures reflect a social catastrophe so extreme the local populations found it difficult to quantify their loss.

The siege of Baghdad took place in early 1258 at Baghdad, the historic capital of the Abbasid Caliphate. After a series of provocations from its ruler, Caliph al-Musta'sim, a large army under Hulegu, a prince of the Mongol Empire, attacked the city. Within a few weeks, Baghdad fell and was sacked by the Mongol army—al-Musta'sim was killed alongside hundreds of thousands of his subjects. The city's fall has traditionally been seen as marking the end of the Islamic Golden Age; in reality, its ramifications are uncertain.
After the accession of his brother Möngke Khan to the Mongol throne in 1251, Hulegu, a grandson of Genghis Khan, was dispatched westwards to Persia to secure the region. His massive army of over 138,000 men took years to reach the region but then quickly attacked and overpowered the Nizari Ismaili Assassins in 1256. The Mongols had expected al-Musta'sim to provide reinforcements for their army—the Caliph's failure to do so, combined with his arrogance in negotiations, convinced Hulegu to overthrow him in late 1257. Invading Mesopotamia from all sides, the Mongol army soon approached Baghdad, routing a sortie on 17 January 1258 by flooding their camp. They then invested Baghdad, which was left with around 30,000 troops. (Full article...)
The rulers of the Yuan dynasty were nominally superior to those of the other three post-Mongol states, but each was de facto independent of the others and occupied with their own territories. The Yuan dynasty adopted Han political traditions, including the use of posthumous names, temple names and era names. Aside from the title of emperor, Yuan rulers also concurrently held the title of khagan. (Full article...)
The city of Bukhara was a major centre of trade and culture in the Khwarazmian Empire, but was located far from the border with the Mongol Empire, and so the Shah had allocated fewer than 20,000 soldiers to defend it. A Mongol force, estimated to number between 30,000 and 50,000 men and commanded by Genghis himself, traversed the Kyzylkum Desert, previously considered impassable for large armies. Bukhara's defenders were caught by surprise and, after a failed sortie, the outer city surrendered within three days on 10 February. Khwarazmian loyalists continued to defend the citadel for less than two weeks, before it was breached and taken. (Full article...)

The Baljuna Covenant was an oath sworn in mid-1203 AD by Temüjin—the khan of the Mongol tribe and the future Genghis Khan—and a small group of companions, subsequently known as the Baljunatu. Temüjin had risen in power in the service of the Kereit khan Toghrul during the late 12th century. In early 1203, Toghrul was convinced by his son Senggum that Temüjin's proposal of a marriage alliance between his and their families was an attempt to usurp their power. After escaping two successive Kereit ambushes, Temüjin was cornered and comprehensively defeated at the Battle of Qalaqaljid Sands.
Temüjin regrouped the scattered remnants of his forces and retreated to Baljuna, an unidentified river or lake in south-eastern Mongolia. There, he and his closest companions swore an oath of mutual fidelity, promising to share hardships and glories. Having spent the summer recruiting warriors attracted by the ideals of his campaign, Temüjin amassed enough of a force to defeat the Kereit in battle that autumn. Three years later in 1206, having defeated all enemies on the steppe, Temüjin entitled himself Genghis Khan at a kurultai and honoured the Baljunatu with the highest distinctions of his new Mongol Empire. Nineteenth-century historians doubted the episode's historicity because of its omission (probably on account of the heterogeneity of the oath-swearers) from the Secret History of the Mongols, a 13th-century epic poem recounting Temüjin's rise.

Shigi Qutuqu (Mongolian: ᠰᠢᠭᠢᠬᠤᠲᠤᠭ; c. 1178–1260) was a high-ranking official during the early decades of the Mongol Empire. The adopted son of the empire's founder Temüjin (later entitled Genghis Khan) and his wife Börte, Shigi Qutuqu played an important role in the codification of Mongol law, serving with distinction as an administrator in North China. He may also have been a major source for the Secret History of the Mongols, which portrays him very favourably.
Although the Secret History states that Shigi Qutuqu was adopted by Hö'elün, Temüjin's mother, chronological inconsistencies make this account improbable. The foundling was brought up in Temüjin's household and was one of the first Mongols to become literate. The Secret History exaggerates his role in the years after the empire's foundation, but Shigi Qutuqu was nevertheless appointed to several high-ranking legal positions, in which he served during the Mongol conquest of the Jin dynasty. He was the commander during the only Mongol defeat of the western campaign against Khwarazmia, being overcome by Jalal al-Din at the 1221 Battle of Parwan. (Full article...)
In recognition of this and other achievements, Boroqul became a member of Genghis' inner council and one of his most trusted advisors alongside Bo'orchu and Muqali. Boroqul died on a campaign against the northern Tumed tribes in 1217, but his achievements meant his clan remained prominent leaders in the Mongol Empire for centuries. (Full article...)
Born between 1155 and 1167 and given the name Temüjin, he was the eldest child of Yesugei, a Mongol chieftain of the Borjigin clan, and his wife Hö'elün. When Temüjin was eight, his father died and his family was abandoned by its tribe. Reduced to near-poverty, Temüjin killed his older half-brother to secure his familial position. His charismatic personality helped to attract his first followers and to form alliances with two prominent steppe leaders named Jamukha and Toghrul; they worked together to retrieve Temüjin's newlywed wife Börte, who had been kidnapped by raiders. As his reputation grew, his relationship with Jamukha deteriorated into open warfare. Temüjin was badly defeated in c. 1187, and may have spent the following years as a subject of the Jin dynasty; upon reemerging in 1196, he swiftly began gaining power. Toghrul came to view Temüjin as a threat and launched a surprise attack on him in 1203. Temüjin retreated, then regrouped and overpowered Toghrul; after defeating the Naiman tribe and executing Jamukha, he was left as the sole ruler on the Mongolian steppe. (Full article...)

A statue of Jochi in modern-day Mongolia
Jochi (Mongolian: ᠵᠦᠴᠢ; c. 1182 – c. 1225), also known as Jüchi, was a prince of the early Mongol Empire. His life was marked by controversy over the circumstances of his birth and culminated in his estrangement from his family. He was nevertheless a prominent military commander and the progenitor of the family who ruled over the khanate of the Golden Horde.
Jochi was the son of Börte, the first wife of the Mongol leader Temüjin. For many months before Jochi's birth, Börte had been a captive of the Merkit tribe, one of whom forcibly married and raped her. Although there was thus considerable doubt over Jochi's parentage, Temüjin considered him his son and treated him accordingly. Many Mongols, most prominently Börte's next son Chagatai, disagreed; these tensions eventually led to both Chagatai and Jochi being excluded from the line of succession to the Mongol throne.

Al-Altan (c. 1196 – 1246), also known as Altalun and Altaluqan, was the youngest child and favourite daughter of Genghis Khan, founder of the Mongol Empire, and Börte, his primary wife. As part of Genghis's policy of marrying his daughters to powerful rulers in exchange for their submission to him, she married Barchuk, the ruler of the wealthy Uighur people to the southwest, in around 1211.
After Genghis died in 1227 and Ögedei Khan, his third son by Börte, ascended to the Mongol throne, it is likely that the Mongol imperial government began to appropriate the territory and taxes of the Uighurs for themselves. When Ögedei died after an extended drinking binge in 1241, Al-Altan was present—she had probably travelled to her brother's court to defend her Uighur subjects. She was rumoured to have poisoned Ögedei, and remained under suspicion until the accession of her nephew Güyük Khan five years later. Shortly afterwards, Al-Altan was put on trial and executed by the general Eljigidei. Although accounts of her life and death were heavily suppressed, with official chronicles compelled to excise or obscure potentially-troublesome details, the injustice of Al-Altan's execution became a major contention during the Toluid Revolution in 1251, when Eljigidei and her surviving accusers were hunted down and killed.

Tolui (c. 1191–1232) was the youngest son of Genghis Khan and Börte. A prominent general during the early Mongol conquests, Tolui was a leading candidate to succeed his father after his death in 1227 and ultimately served as regent of the Mongol Empire until the accession of his brother Ögedei two years later. Tolui's wife was Sorghaghtani Beki; their sons included Möngke and Kublai, the fourth and fifth khans of the empire, and Hulagu, the founder of the Ilkhanate.
Tolui was less active than his elder brothers Jochi, Chagatai, and Ögedei during their father's rise to power, but once he reached adulthood he was considered the finest warrior of the four. He commanded armies under his father during the first invasion of Jin China (1211–1215), and his distinguished service during the Mongol invasion of the Khwarazmian Empire secured his reputation. After the fall of the cities of Transoxiana in 1220, Genghis dispatched Tolui early the following year to subjugate the region of Khorasan, which had begun to cause trouble for the Mongol armies. Tolui executed his orders with ruthless efficiency, assaulting the major cities of Merv, Nishapur, and Herat, and subjugating numerous others. Medieval chroniclers attributed more than three million deaths to the massacres he ordered at Nishapur and Merv; while these figures are considered exaggerated by modern historians, they are evidence of the abnormal brutality of Tolui's campaign.

Oghul Qaimish was born into the Merkit tribe and married Güyük in the 1220s. She played little role in his political activities either before or during his time as khan. After his death, her rule was ineffective and confused, with her sons Khoja and Naqu often acting in opposition to her. Meanwhile, her political opponents Batu Khan and Sorghaghtani Beki comprehensively outmanoeuvred her by having Sorghaghtani's son Möngke elected as khan in 1250. After his accession, Oghul Qaimish was implicated in a failed coup attempt by Naqu—in retaliation to her refusal to submit, Möngke had her imprisoned, allegedly tortured and, after a show trial, executed.

Checheyigen (c. 1186 – after 1253) was the second daughter of Genghis Khan, the founder of the Mongol Empire, and his first wife Börte. As part of Genghis's policy of marrying his daughters to powerful rulers in exchange for their submission, she married a prince of the Oirat tribe, who lived near Lake Baikal, in 1207. There, she assumed a high-ranking administrative role among her husband's people, organising people and flocks like other high-ranking nomadic women. Over the following decades, Checheyigen arranged a series of advantageous marriages for her seven children and, after she backed the successful side in the Toluid Revolution of the early 1250s, her Oirat family became one of the most powerful in the empire. However, her descendants failed to take full advantage of their position, and eventually lost most of their influence. (Full article...)
Born into the Olkhonud clan of the Onggirat tribe, Hö'elün was originally married to Chiledu, a Merkit aristocrat; she was captured shortly after her wedding by Yesügei, an important member of the Mongols, who abducted her to be his primary wife. She and Yesügei had four sons and one daughter: Temüjin, Qasar, Hachiun, Temüge, and Temülen. After Yesügei was fatally poisoned and the Mongols abandoned her family, Hö'elün shepherded all her children through poverty to adulthood—her resilience and organisational skills have been remarked upon by historians. She continued to play an important role after Temüjin's marriage to Börte—together, the two women managed his camp and provided him with advice. (Full article...)
Chagatai Khan (Mongolian: ᠴᠠᠭᠠᠲᠠᠶ; c. 1184 – 1242) was a son of Genghis Khan and a prominent figure in the early Mongol Empire. The second son of Genghis's wife Börte, Chagatai was renowned for his masterful knowledge of Mongol custom and law, which he scrupulously obeyed, and his harsh temperament. Because Genghis felt that he was too inflexible in character, most notably never accepting the legitimacy of his elder brother Jochi, he excluded Chagatai from succession to the Mongol throne. He was nevertheless a key figure in ensuring the stability of the empire after Genghis's death and during the reign of his younger brother Ögedei Khan.
Chagatai held military commands alongside his brothers during the Mongol conquest of the Jin dynasty in 1211 and the invasion of the Khwarazmian Empire in 1219. During the latter, he was appointed to a key role in organising logistics in addition to battlefield responsibilities, but was censured after feuding with Jochi during the Siege of Gurganj. After the campaign, Chagatai was granted large tracts of conquered land in Central Asia, which he ruled until his death. He quarrelled with civil officials such as Mahmud Yalavach over matters of jurisdiction and advised Ögedei on questions of rulership. Chagatai died shortly after Ögedei in 1242; his descendants would rule his territories as the eponymous Chagatai Khanate. (Full article...)
